To fill whom it may concern:

7 Be it known that I, Lns'rnn A. WERNERY, a citizen of the UnitedStates, residing in Brooklyn borough, city of llew York, in the countyof Kings and State of New York, have invented certain new andusefulImprovements in Combined yperWriting and ComputingMachines, oiwhich the followi'ngis a specification.

My invention relates to an improved means to prevent the type-bars of acombined typewriting and computing machine from printing duringcomputation.

An object of the invention is to provide .a device of this characterwhich shall be of simple construction and inexpensive, and at the sametime eilicient and reliable in operation, which may also be veryquiclzly point, so

attached to or removed from the machine or shifted into or out ofoperative position without removal from the machine, andwhich moreoverrequires little or no alteration of the standard forms of machines Astop in the form of a horizontally-disposed rod located adjacent theprinting point, is shiftable vertically into and out of positionsubstantially over the printing that when in effective position it canserve as a stop for the types, and prevent them from printing. When thetype bars are provided with upper and lower said stop preferably engagesthe type-bar between the two types, allowing the typeebar tosubstantially complete its stroke.

The ends of the stop rod are vertically and adjustably supported inupright guiding members removably mounted on the type bar segment.

detents to engage notches in the stop rod to hold it in adjustedposition.

The present invention is a modification of that disclosed in theapplication of W. L. Dench, Serial No. 784,213, filed August 11, 1913,and is'limited to features not disclosed in said application.

Other featuresand advantages will here- In the =eccompan ing drawingswhich illustrate-the. invention as applied to an Underwood-Hansoncombined typewriting tive view of the stop device and associated partsof the machine to hich it is applied.-

and its supports. Fig. 4 is a perspective view of the stop. Fig. 5 is asimilar view of one of the supports.

The typekeys 1 are mounted on levers 2 bell cranks 3 to swing ment 5,upwardly .and rearwardly against the platen 6 onwhi'ch the work-sheet issupported. As the type-bars approach the printing point they enter theusual type guide 7 mounted on the segment 5 and secured 11 position byscrews 8. The numeral.

keys in the form of machine herein shown are provided with pendents 9tostrike bell cranks 10, so as mechanism (not shown) the numbersrepstruclz. If it is desired to set up numbers without printing them onthe platen, a stop 11 is moved into position tointercept the typebarsbefore they reach the printing point.

The stop is preferably formed from a wire rod having a horizontal stopportion and depending members vertically adjustable in. guiding,supports 13, mounted on the segment 5. The. supports 13 comprisevertical side plates 1 1 spaced to receive the members 12 of the stop.On each support 13 is secured a leaf spring 15 having its upper end 16rolled to The lower. ends of the stop .rod 11 have llOllZOIltfll forwardprojections 20 adapted to engage the lowerpins l9 and thereby form apositive means to prevent accidental removal of the stop from itssupports. Horizontal sections 21 of the members 12- offset the stop 11rearwardly to bring it in to set up on computing 12 supported and closeproximity to the platen. The supports 13 may be removably attached tothe segment 5 by means of dowel pins 22 adapted to enter suitableopenings in the segment, and so positioned that the flat sides of thesupports will bear against the sides of the type guide 7 and thus holdthe supports '13 against rotation. This construction' permits the stop11 and its guiding supports 13 to be instantaneously attached to orremoved from the machine. Also in the type of machine shown noalteration of lll the machine is requirged to adapt it for theattachment, as such machines are provided with holes drilled in thesegment 5 for the attachment of card holders and the like,

which holes serve for the dowel 22 in the present invention.

It will be noted that when the stop 11 is in its lowered or operativeposition, as shown in Fig. 2, it extends directly between the upper andlower case types and the actuated type bar. The type-bar is thuspermitted to practically unchanged by the use of the stop 11, and thetypes are permitted to strike the universal bar 23 and operate theescapement mechanism controlled thereby in the usual manner;

While the stop 11 is in use, the spring detents 16 engage the notches 17and hold the stop in operative position. When it is desired todiscontinue the use of the stop, it is simply pulled upwardly untilthedetents 16 snap into the lower notches 18.

The entire device may at any time be removed by simply lifting thesupports 13, together with the stop 11 as a'unit, fromthe machine. Y

Variations may be, resorted to within the scopeof the invention, andportions of the improvements may be used witheut others.

Having thus described my invention, I claim:

v1. In a combined typewriting and computing machine, the combinationwith a rotatable platen, of a type-bar having upper and lower case typestherein, and a stop in position to engage the type-bar between saidtypes during the printing'stroke and thereverse to the platen axis intoand out of positatable platen andty'pe-bars to strike the by preventprinting.

2. In a combined typewriting and computing machine, the combination witha retatable platen and type-bars, of a stop rod extending in thedirection of the platen axis and bodily movable in a direction transtionto intercept the type-bars.

3. In a combined typewriting and computing machine, the combination witha horizontally-disposed rotatable platen and type-bars adapted to swingupwardly and forwardly to strike the front. face of the platen, of ahorizontal stop rod extending along the face of the platen adjacent totheprinting point, and guides in which said rod is vertically movableinto and out of position to stop thetype-bars as they approach theprinting point.

In a combinedv typewriting and computing machine, thecombination with a rotatable platen and type-bars to strike the platen,of a stop rod extending across the path of the type-bars and on oppositesides of the printing point, depending guiding members on said rod, andstationary supports in which said members are supported and verticallyadjustable into and out of the path ofthe type-bars to bring'said stopinto 'and'out of position to stop the type bars.

6. In a machine of the character described, the combination with atypewriter platen and type-bars, of a, stop rod movable into and out ofposition to stop the typebars, andsupports in which the stop isadjustably mounted.

7. In a machine of the character described, the'combination' with aplaten, a type-bar segment and type-bars, of a stop,

9. In a machine of the character described, the combination of atype-bar segment, a stop rod, supporting and guiding members for thestopro'd, said members having dowel pins to enter openings in thesegment and thereby removably support said members on the segment, and atype guide mounted on the segment and bearing against said members,thereby preventing rotary movement of the said members.
